Detailed description of the invention
Fig. 1 is the functional block diagram of the electronic installation shown by one embodiment of the invention。Fig. 2 is the part-structure schematic diagram of the electronic installation shown by one embodiment of the invention。Refer to Fig. 1 and Fig. 2, electronic installation 10 includes antenna 11, metal edge frame 12, sensing circuit 13, control circuit 14, adjusts circuit 15, earth element 16 and signal source 17。In the present embodiment, electronic installation 10 is such as various portable electron devices or the mobile communications devices such as mobile phone (cellphone), personal digital assistant (PersonalDigitalAssistant, PDA), smart mobile phone (smartphone), e-book (electronicbook), game machine (gamemachine) or panel computer (TabletPC)
As in figure 2 it is shown, earth element 16 is provided on a surface of substrate 21。Additionally, the region being not provided with earth element 16 on this surface of substrate 21 will be regarded as empty regions 211, and antenna 11 is provided in empty regions 211。In the present embodiment, antenna 11 is such as planar inverted F-shape antenna (planarinverted-Fantenna, PIFA) or loop aerial (loopantenna) ... wait the antenna having feed side 111 with earth terminal 112。But, in another embodiment, antenna 11 can also is that unipole antenna (monopoleantenna) etc. only has the antenna of feed side 111, and the kind of antenna 11 is not limited by the present invention。
Metal edge frame 12 is looped around the surrounding of substrate 21。In the present embodiment, metal edge frame 12 is such as a part for the housing of electronic installation 10。Such as, if electronic installation 10 has upper shell and lower house, then metal edge frame 12 can be a part for upper shell or lower house, or is arranged between upper shell and lower house。Additionally, the metallic character (such as, metallic luster) of available metal edge frame 12 promotes the texture of electronic installation 10 itself。But, in another embodiment, the metal edge frame 12 of part can also be taken as a part for antenna 11, and related implementation detail is detailed later。
Sensing circuit 13 is arranged on the base plate (21, and can include sensing element 131_1～131_n, and the quantity of sensing element 131_1～131_n is determined by the demand in cost, practical application or design。For the sensing element 131_1～131_8 in Fig. 2, sensing element 131_1～131_8 is such as provided on substrate 21, and is respectively adjacent to or abuts against metal edge frame 12。Thus, sensing element 131_1～131_n will may be used on detection metal edge frame 12 or whether there is object about。Object can be human body (such as, finger and/or palm) or various conductive species referred in this。For example, when user grips electronic installation 10, the finger of user and/or palm may touch metal edge frame 12。When the finger of user and/or palm close to or when touching metal edge frame 12, sensing element 131_1～131_8 will produce the induced signal of correspondence。
It is noted that the one that the sensing element 131_1～131_8 in Fig. 2 is only sensing element 131_1～131_n implements example。In other examples, if being intended to improve the degree of accuracy of detection, then the quantity that can pass through increase sensing element 131_1～131_8 or the position (such as, closer to metal edge frame 12) that arranges changing sensing element 131_1～131_8 are reached。Additionally, the kind of sensing element 131_1～131_n can also depending on the demand in practical application or design with embodiment。Such as, in the present embodiment, sensing element 131_1～131_n can be capacitance type sensing element。
Then, sensing circuit 13 decides whether that according to the testing result of sensing element 131_1～131_n the sensing signal transmitting sensing element 131_1～131_n is to control circuit 14。For example, sensing circuit 13 may also include a judging unit 132, in order to the testing result according to sensing element 131_1～131_n, judges whether the surrounding of metal edge frame 12 exists object。When there is object in the surrounding that the judged result of judging unit 132 is metal edge frame 12, it is judged that the sensing signal of unit 132 meeting self-inductance measurement element 131_1～131_n in the future is sent to control circuit 14。Otherwise, if judging unit 132 judges surrounding's not object of metal edge frame 12, then judging unit 132 persistently receives the testing result of sensing element 131_1～131_n and performs above-mentioned judgement step。
In the present embodiment, when all or part of sensing element 131_1～131_n (such as, sensing element 131_1～131_8) produced by the size of sensing signal or amount of change more than a threshold value time, then represent that the surrounding of metal edge frame 12 has object to exist, or have object to touch metal edge frame 12 (such as, the finger of user touches the metal edge frame 12 of part)。Now, it is judged that the sensing signal of unit 132 meeting self-inductance measurement element 131_1～131_n (such as, sensing element 131_1～131_8) in the future is sent to control circuit 15。In other words, can pass through to analyze these sensing signals and just be appreciated that distance general between above-mentioned object (such as, finger) and metal edge frame 12 and/or contacting points position etc.。
